(Annajm) 53 : 23
إِنْ هِيَ إِلَّا أَسْمَاءٌ سَمَّيْتُمُوهَا أَنْتُمْ وَآبَاؤُكُمْ مَا أَنْزَلَ اللَّهُ بِهَا مِنْ سُلْطَانٍ ۚ إِنْ يَتَّبِعُونَ إِلَّا الظَّنَّ وَمَا تَهْوَى الْأَنْفُسُ ۖ وَلَقَدْ جَاءَهُمْ مِنْ رَبِّهِمُ الْهُدَىٰ

It is nothing except the names you and your forefathers named, for which Allah hasn’t sent down any Authority about them; indeed they are not following anything except conjectures and their souls’ whims, while surely the Guidance from their Lord has come to them.

Even though Adhikr which is the Guidance from the Lord of the universe has come to them through their honest companion, they were only following their whims and guessing. What they had been serving was only some names which they and their forefathers were naming, and Allah had not sent any authority for them.
The disbelievers during the period of Messenger Muhammed were demanding for a codified Book Adhikr. Today Adhikr which is the Best Interpretation of Lord’s Book mentioned in verses 25: 33-34 is codified as a Book. But the Arabic Qur’an Reading Fujjar who are mentioned as worthless people in verses 25: 18 and 48: 12, and who has made their food rejecting Adhikr as told in verse 56: 82 are hastening for the end of the world by not utilising It themselves and not giving It to utilise for others as explained in verse 6: 26. See explanation 34: 19-20; 45: 23-24; and 46: 34-35.
